Abstract
PURPOSE: To conduct sealing excellent in responsibility, strength in sealing holes on the end face of a resin pipe provided with a number of axial holes on the pipe wall by a method wherein pressure in given in heating to the end face in an axial direction and the holes on the end face are contracted and then sealing plastic pieces are heated and welded with the end face of the pipe.
CONSTITUTION: In sealing of the end face of a perforated plastic pipe 1 provided with a number of axial holes 11 on the pipe wall, the end part of perforated plastic pipe 1 is inserted into a heating ring 2 having a ringed projection 22, heated and pressed in an axial direction to contract or close the holes 11 on the end face, to increase the thickness of the end face b of the intermediate layer 1b of the pipe wall and to form sealing tubular pieces a, c. The end of the perforated plastic pipe 1 is forced into a die 3 having a U-section, the sealing tubular pieces a, c are butt- welded and weld with the end face b of the intermediate layer to seal the holes 11 on the end surface of the pipe.
